PROBLEM TO BE SOLVED: To perform distortion compensation by a digital system to the respective amplitude components and phase components of transmission signals. SOLUTION: This digital system distortion compensation device is comprises a distortion compensation means 1 for executing distortion compensation processing based on a compensation amount 13 to be set in response to a first signal 7 and generating a second signal 9, a transmission means 3 for executing quadrature modulation to the second signal 9, generating a third signal and generating a fourth signal 11 from the third signal and a control means 5 for controlling the distortion compensation means 1, based on the distortion of the fourth signal 11. |
